i dont see their potential to beat a 660T (i dont mean all and i definitely dont mean yours ya). for all i know, the concept of building a 850T is almost the same as plug and play a L2, but a combination of gearbox system, turbocharger system and electronic controller system have to be right in order to unlease the potential of 850T (since it's a custom job and it's not the manufacturer that produce that spec, u have to research to get the spec right for your application)
i hope you agree with me on this
